I have a 10 week old pup who is great with my other dogs but just lately my 5 year old dog keeps cocking his leg and peeing over him. Yesterday he did this over his ears and today it was his back end. I know he is marking but why is he marking the pup?
Could it be a protective thing in that he is scent marking to pup as an ownership kind of thing. I have read somewhere that some dogs do this to their owners and it is a sign of ownership.
